Opportunistic Link Scheduling with QoS Requirements in Wireless Ad Hoc Networks
— In this paper, we study the link layer scheduling problem in wireless ad hoc networks. In such a network, the communication links compete for the scarce and time-varying wirele...

On Myopic Sensing for Multi-Channel Opportunistic Access
We consider a multi-channel opportunistic communication system where the states of these channels evolve as independent and statistically identical Markov chains (the Gilbert-Elli...

On myopic sensing for multi-channel opportunistic access: structure, optimality, and performance
We consider a multi-channel opportunistic communication system where the states of these channels evolve as independent and statistically identical Markov chains (the Gilbert-Elli...

On the Analysis and Design of Practical Quantization for Opportunistic Beamforming
Abstract—We propose a closed–loop scheme that combines opportunistic beamforming (OBF) and closed–loop (CL) transmit–diversity (TD) techniques. This quantized OBF scheme is...
